The thermal strain imposed on helicopter aircrew by chemical protective (NBC) clothing in summer in Germany has been assessed in a laboratory simulation. The environmental conditions used were dry bulb temperature 35 degrees C, wet bulb temperature 19 degrees C and a wind speed of 2.0 m X s-1. The NBC equipment imposed a significant thermal strain on the crewman when compared with standard summ...

There is much empirical evidence about the success of naive Bayesian classification (NBC) in medical applications of attribute-based machine learning. NBC assumes conditional independence between attributes. In classification, such classifiers sum up the pieces of classrelated evidence from individual attributes, independently of other attributes. The performance, however, deteriorates signific...

In this paper, we propose a semantic naïve Bayes classifier (SNBC) to improve the conventional naïve Bayes classifier (NBC) by incorporating “document-level” semantic information for document classification (DC). To capture the semantic information from each document, we develop semantic feature extraction and modeling algorithms. For semantic feature extraction, we first apply a log-Bilinear d...

[1] Eight years of TOPEX/Poseidon altimeter-derived sea height anomaly and climatological hydrographic data are used to investigate the temporal and spatial variability of the North Brazil Current (NBC) retroflection and the North Equatorial Countercurrent (NECC). The NBC retroflection exhibits a mean position of 6.6 N± 2.0 , with a strong annual signal and year-to-year variability. The annual ...

Nanocrystalline niobium carbide (NbC) ceramics and carbide-niobium nitride (NbC/NbN) composites were synthesized at low temperatures without high-pressure sintering using a single-step polymer-derived approach from meltable pre-ceramic blend. Niobium hydride (NbH5) 1,2,4,5-tetrakis(phenylethynyl)benzene (TPEB) reacted 1500 °C under argon or nitrogen in tube furnace to form NbC NbC/NbN with high...

Isolated mitochondria-rich (MR) cells from the rainbow trout gill epithelium were subjected to intracellular pH (pH(i)) imaging with the pH-sensitive dye BCECF-AM. MR cells were categorized into two distinct functional subtypes based on their ability to recover pH(i) from an NH(4)Cl-induced acidification in the absence of Na(+). An apparent link between resting pH(i) and Na(+)-independent pH(i)...
